Abstract:
New aminium compounds having an excellent solubility in solvents, being highly safe in handling and for the environment, and represented by general formula (1), (wherein R�1? is a substituted or unsubstituted alkyl group; and A�2? is a divalent organic anion) , and optical recording media containing the same. These compounds have a high solubility in organic solvents particularly when they are used together with dyes, and solutions thereof have a high storability.
